It was reported that the singer was profoundly affected by the suicide by hanging last May of his close friend, Soundgarden and Audioslave lead vocalist Chris Cornell, who would’ve been 53 the day of Bennington’s death.

Brian Elias, chief of operations for the Los Angeles County Department of Medical Examiner, told Rolling Stone that more information will be released next week Thursday after conducting a death investigation.

Fans and fellow musicians quickly expressed sorrow at the singer’s sudden death on social media.

Bennington, and the rest of Linkin Park are behind hit songs such as “In The End”, “Numb” and “One Step Closer”. He also served as lead vocalist for Stone Temple Pilots, the side project Dead by Sunrise and supergroup Kings of Chaos.

The singer has struggled with drug and alcohol addiction in the past. In an interview, he also revealed he was sexually abused as a child by an older male friend which resulted to his frequent contemplation to commit suicide.
